In our continuing series Talking Schmidt we bring you the most insightful lines from Google Chairman Eric Schmidt.

Schmidt, who is promoting his new book The New Digital Age, spoke with NPR over the weekend on the Wait Wait… Don’t Tell Me! program in a rather lighthearted appearance.

NPR host Peter Sagal asked the executive chairman how much Google knew about its users at the top of show, which prompted Schmidt to admit, “Well, as much as you’ll let us know.”

Schmidt also mentioned that the company really doesn’t quite know the definition of evil, from its famous slogan “Don’t Be Evil,” and that he thought it was “the stupidest rule ever” when he joined the company.
